Summary

Summary

With low computational complexity and relatively short development time, Fuzzy Logic is an indispensable tool for engineering applications. The field is growing at an unprecedented rate, and there is a need for a book that describes essential tools, applications, examples, and perspectives in the field of fuzzy learning. The editors of Fuzzy Learning and Applications fill this need, providing an essential book for researchers, scientists, and engineers alike.

Organized into four parts, this book starts with the simplest learning method and gradually arrives at the most complex. First, it summarizes all the symbols and formulae used in the succeeding chapters and presents a historical overview of fuzzy learning. Next, it deals with current techniques, ranging from deterministic to hybrid methods. It then illustrates the enormous number of possibilities offered by fuzzy learning. Finally, it covers hardware dedicated to fuzzy learning, from digital to analog designs and implementations. With Fuzzy Learning and Applications, readers will discover the enormous possibilities fuzzy learning offers.

Choice Review

Each of the 11 chapters of this book is a report by the author or authors of the chapter describing advanced research in the area of fuzzy learning and its applications. The list of chapter headings indicates the scope of the research: "Evolutionary Fuzzy Learning" (describing the fusion of neural networks and genetic algorithms for fuzzy learning), "Fuzzy Controller Chip with Supervised Learning Capabilities," "Fuzzy Modeling in a Multi-Agent Framework," "Learning Techniques for Supervised Fuzzy Classifiers," "Multistage Fuzzy Control," "Learning Fuzzy Systems," "Use of Fuzzy Modeling in the Analysis of Rowing Speed," "Hopfield Coefficient Determination," "Fuzzy Control of a CD Player Focusing System," "Neuro-Fuzzy Scheduler for a Multimedia Web Server," and "A Neuro-Fuzzy System Based on Logical Interpretation of Fuzzy If_Then Rules." This book would be an excellent resource for graduate students and advanced researchers in two ways: it would enable them to learn about some of the advanced research and applications being carried out, and would provide them with a variety of ideas for further research and applications.
